Description

Technical Field

[0001] The utility model relates to the technical field of soil heavy metal analysis, in particular to a soil heavy metal analyzer which is convenient to grasp and hold. Background Art

[0002] The soil heavy metal analyzer can be used for on-site analysis of various types of environments. Its functions include on-site analysis of "original soil" for rapid on-site soil surveys and applications in soil and water conservation projects. Operators can directly use the analyzer to analyze the land on site, or through sampling, analyze bagged samples. By collecting, processing and analyzing soil samples on site, the same analysis results as in the laboratory can be achieved on site. Fine particulate matter is also called fine particles, fine particles, PM2.5. Fine particulate matter refers to particles in the ambient air with an aerodynamic equivalent diameter of less than or equal to 2.5 microns. It can remain suspended in the air for a long time. The higher the concentration in the air, the more serious the air pollution.

[0003] At present, when detecting the heavy metal content in the soil, the soil metal analyzer needs to maintain a certain distance to avoid possible interference caused by direct contact with the soil. This gap can reduce the impact of soil particles, impurities or other factors on the measurement results of the analyzer, thereby improving the measurement precision and accuracy. Therefore, X-ray fluorescence is easy to irradiate all around. Long-term exposure to X-ray fluorescence will have a certain impact on the body of workers. Therefore, a soil heavy metal analyzer that is easy to grasp and hold is proposed. Utility Model Content
